I haven't made a decission yet, but I was in PepBoys today so I thought I'd
check out their kit. Nothing on the floor so I ask an employee. He has no
idea what I'm talking about so he attempts to look it up on the computer,
but he can't find it there. I ask him if he knows where any little cans that
read "R134a" are. That worked. They are practically right behind him on an
endcap behind the counter. I see the kit so I tell him "there it is on the
right" (we're both facing the endcap), but he looks more towards the left. I
correct him, "on the right". He moves further left. Obviously I had made the
mistake of not telling him it was on his other right. From there it was
almost a game of warmer/colder.
